Payment merchants for recurring payments

Hello guys, do you know any payment merchants for recurring payments? What else exist besides stripe?

I tried making my own list, here is what i found:

Stripe
PayPal
Braintree
Chargebee
Recurly
GoCardless
Adyen
HubSpot
Checkout
BlueSnap
Worldpay
FreshBooks
Zuora

Are there any others? What is your opinion about these?

I currently use stripe, but want to have more than 1 payment merchant, so wondering which ones are not too hard to apply for..
